VETERINARY INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 430,137., dated June 17, 1890. Application filed September 9, 1889. Serial No. 323,356. (No model.)

To all whom it may concern.-

Be it known that I, SANDFORD 0.1VIEDDICK, a citizen of the United States, residing at Ovid, in the county of Seneca and State of New York, have invented certain new and usefullmprovements in Veterinary Instruments for Aiding Conception in Mares, of which the following is a specification.

My invention relates to a Veterinary instrument whereby mares and other female animals are aided in conception.

Heretofore great difficulty has often been experienced in getting mares to conceive properly. Very often in mares during the act of coition the mouth of the uterus is closed at a time when it is necessary that it should be open, and remains closed for quite a while, sufficiently long to prevent conception taking place. It has also been noticed that mares after coition very often strain or force the semen from the uterus and vagina and thereby frustrate all intended objects.

The object of my invention is to remedy the above-mentioned evils and to produce an instrument which shall be simple in construction and operation, easily applied, and one that is not injurious in its application.

With these objects in view my invention consists of a soft-rubber funnel adapted to be inserted and retained in the neck of the uterus, and a hard-rubber tube adapted to fit into the soft-rubber funnel.

It consists, further, in the novel construction and arrangement of the various parts, as will be more fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which similar letters of reference indicate similar parts, Figure 1 is a perspective view showing the relative arrangement of the parts, the hardrubber tube being drawn slightly outward. Fig. 2 is a perspective View of the soft-rubber funnel. Fig. 3 is a perspective View of the hard-rubber tube. Fig. 4 is a vertical longitudinal sectional View of the tube and funnel. Fig. 5 is a sectional view showing method of application.

In the embodiment of my invention I employ a funnel A of soft rubber, but sufficiently stiff to accomplish the purpose for which it is intended. The said funnel is formed with a broad mouth a, said mouth being quite shallow, as shown, and attached to the contracted portion of said mouth is the neck of the funnel a ,the sides of said neck extending a considerable distance from the mouth a, and throughout the entire length of the neck it is of a uniform diameter; but I preferably contract the lower end, as shown, the purpose of which will appear farther on. Upon the exterior surface of the neck a are arranged at suitable intervals the transverse parallel rings B, said rings being secured to the neck in any suitable manner, and attached to the said rings are the oblique annular flanges or fins C, said flanges or fins being quite thin and extending outwardly at an angle to the sides of the neck and upwardly toward the mouth of the funnel.

The soft-rubber funnel A is inserted in the mouth and neck of the uterus, the neck of the funnel extending into the neck of the uterus, and the mouth of the funnel covers the mouth thereof and being flexible conforms to the shape of the contacting-walls of the vagina in case it is brought in contact with the same. The contracted end of the neck greatly aids in introducing the same, and the oblique fins serve to hold the funnel securely in the neck of the uterus, and also prevents the mare from straining, as in said act it is necessary to contract the uterus, but the friction of the fins will tend to prevent this. WVithin the funnel A is inserted a hardrubber tube D, said tube being of an external diameter equal to the internal diameter of the neck of the funnel, one end of said tube being flared at d, corresponding to the flare of the mouth of the funnel a, and at its opposite end said funnel is contracted, as at d, whichcorresponds to the contracted end a. WVhen the hard-rubber tube is inserted in the funnel, every exterior portion of it lies in close contact with the soft-rubber funnel, as shown in Figs. 4 and 5. The hard rubber tube being inserted in the funnel, it is impossible for the mare to strain and close the mouth of the uterus, and it will be seen that the semen introduced into the Vagina will be safely guided into the uterus, thus insuring conception.

The instrument can be quickly and easily applied and detached, and is safe in operation and does not injure the mare either in inserting or removing the same.

From the above description of the various parts its operation and advantages are apparent to all skilled in the art to which it pertains. While I have given specific constructions of the various parts in the description of my invention, I do not confine myself to such constructions, but may Vary the same without departing from the broad principles of my invention. Neither do I confine 1nyself to the use of the materials named, but may use any flexible and inflexible substances suitable for the purposes described. Either of the partsthe tube or funnel may be used independent of the other; but the method shown and described is the preferred one.

Having thus described my invention, What I claim is- 1. In a veterinary instrument, the combination, with an inflexible tubular portion, of an outer tubular portion embracing or encircling the inflexible tubular portion and provided with a series of annular flexible flanges for retaining the inflexible tubular portion in position during use of the instrument.

2. In an improved Veterinary instrument, the combination, with a soft-rubber funnel constructed as described, of the transverse rings surrounding the neck of said funnel, the oblique annular flanges or fins attached to the transverse rings, and a hard-rubber tube constructed as described, adapted to be inserted in the funnel, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
